PROFILE
Tatsuya Yamaguchi
Susumu contributed to the ArduPilot/ardupilot repository by developing and refining features across embedded systems, simulation, and sensor integration. Over four months, Susumu enhanced telemetry reliability by fixing temperature conversion logic for the SCHA63T sensor and implemented dynamic node ID updates for DroneCAN battery monitors, reducing downtime during hot-swaps. In simulation, Susumu added RPLidarS2 support to SITL, improving robotics testing fidelity, and introduced configurable Vicon odometry quality for MAVLink data. Additionally, Susumu improved code maintainability by clarifying pre-arm check naming and streamlined the UI by hiding payload parameters when not in use, using C++ and firmware development expertise.

Dec 1, 2025Month: 2025-12 focused on delivering high-value sensor simulation improvements for ArduPilot. Key accomplishment: added simulated RPLidarS2 support in SITL to enable more realistic lidar data in robotics simulations, including enhancements to sensor scanning modes and data handling for dense express scans to improve fidelity and processing efficiency. This work strengthens the SITL simulation pipeline, enabling safer, faster validation of perception stacks and mission planning in a simulated environment.

Nov 1, 2025In 2025-11, focused on safety and naming clarity in OpenDroneID. Delivered a feature refinement by renaming EnforceArming to EnforcePreArmChecks to better reflect pre-arm checks. This change was implemented in ArduPilot/ardupilot with commit f29b062e408d52fd39117a5292bdba4f44834f17, improving code readability, reducing risk of misinterpretation during pre-arm sequences, and easing developer onboarding. No major bugs fixed this period; the focus was on safety posture and maintainability.

Apr 1, 2025April 2025 monthly summary for ArduPilot/ardupilot highlighting two key deliverables that improved reliability and data quality: - SCHA63T Temperature Reporting Bug: Accurate Temperature Conversion — fixed by casting the temperature value to a signed 16-bit integer before use, improving the accuracy of temperature reporting. Commit: a1b201414220c73d90da8df139d0bfe0e30921e2. - DroneCAN Battery Monitors: Dynamic Node ID Updates During Hot-Swapping — added dynamic node ID updates for DroneCAN battery monitors when hot-swapping; if a battery's ID matches but the node ID is lost and dynamic updates are enabled, the system updates the node ID and re-initializes telemetry to resume monitoring. Commit: ebc7e1349d10ec723315966f601e5e7b65e6a879. Impact: improved sensor data fidelity and telemetry continuity with reduced downtime during hot-swaps. Demonstrates competence in embedded C/C++, sensor data handling, telemetry management, and dynamic configuration.
